do you mean electronic actuator? and which one there are so many?

Cylinder misfire on #2 cylinder, Takes all to fire a cylinder (Fuel, Spark, Air & Timing) properly. Easiest to check is spark. Pull the plug and look at it. Is it wet and smell like fuel? If so, then swap it with cylinder next to it. If the problem moved, then its the plug. If the misfire is still on Cylinder #2, then swap the plug wire (both ends). If the misfire is still on Cylinder #2, then swap the coil. (see where this is going?) If the plug is dry, then check the fuel injector for operation. Noid light tester or you can get a long screwdriver and stick one end on your ear and the other on the injector - it should make a steady, rhythmic clicking sound if it is functional when car is running. No sound? Replace. Is the plug oily? Check cylinder #2 for compression. No compression or little compression means either head gasket blown or bad/sticking valve (intake or exhaust) = big money to get fixed. Timing on one cylinder is hard to test without correct test tools. Timing is likely not a problem on a single cylinder misfire. Good luck.

Have you tried fixing the errors that the ECU is reporting?

Sounds like the mechanic who changed the Cat Converter hit the wires to the oil sending unit or a metal shield on the engine that needed to be removed to replace the Cat was not put back properly and is so loose it is hitting the wire to the oil sensor... Get it checked out by a RELIABLE mechanic...

Could be the throttle cable is loose or stretched , try adjusting the tension on the cable making sure not to tighten it too much as this could cause the butterfly valve to be slightly open which will increase idle speed.

Sounds like blocked fuel line. Happens often when the car is ran on nearly empty tank. All the junk at bottom of tank gets sucked into system. Unblock fuel line. Red.

Hi Robin- There are two fuses for the radio in a 2004 Nissan Sentra. Fuse #6 in the fuse box inside the cabin, and #31 in the fuse-fusible link box next to the battery. Hope this helps!

Your belt may be loose and not turning the water pump enough to circulate the coolant causing it to run hot,crank car up, have some one press gas pedal and watch belt turn,if not turning tightly,then belt or tensioner is bad.

Many auto parts stores will read out the codes for you free of charge.

There are 2 bulbs above the license plate, each under a plastic cover. The covers are held in with 2 screws each. Just unscrew and remove the plastic covers and you should be able to access the bulbs.

I have the same problem. Are the tabs holding the bulb in the socket broken? Splice in a used socket from a junked vehicle, or use some Gorrilla (R) tape to hold it more firmly in the socket. It is stickier than duct tape.

Do you have a CVT? (Continuosly Variable Transmission) I doubt that you do so if you dont, nissans are known to have hard shift into second gear you mean.(Once the car moves, its already in first gear) so if it shifts fine into other gears, I wouldnt worry too much unless it gets worse.

Hi Cathy,is your bulb good.If so,then check the switch at the doors,push in with your hand and see if it is releasing.Is there a switch at the dash?Open the other doors one at a time and see if the light comes on,if so then switch at driver's door is bad.You can get a meter and check it at the light to see if power is their.Also can check the switch with meter to see if power is there,if it is,then bad switch.
